[Brain Aldiss] began publishing his stories in the mid-1950s, a time when SF was heavily dominated by US writers schooled in the markets of commercial magazines. Aldiss’s work came as a breath of fresh air to a genre beginning to suffocate in its own orthodoxies. He wrote lively, intelligent prose, shot through with subversive humour, linguistic novelty and human observation. He took for his subjects the full range of modern scientific research. As well as the exact sciences, he also plundered speculative, psychological, sociological and sexological areas of inquiry. One of the most exhilarating aspects of reading Aldiss is the diversity of his imagination.
